why is it different to see the particles of solute and solvent in a true solution whereas they can be seen easily in a suspension
Answers
Answer:In true solutions, particles are invisible through the naked eye. The particles in the colloidal solution are visible through the electron microscope, but not through the naked eye. The particles in the suspension are visible through naked eyes as well as under the electron microscope.

Answer:
The true solution is the homogenous mixture, while Colloidal solution and Suspension are the heterogeneous mixtures of two or more substances. Another difference between these three types of solution is that the True solution is transparent, while the Colloidal solution is translucent and Suspension is opaque.
Concerning chemistry, Solutions can be defined as the mixtures of two or more substances, where the solvent is in the liquid form, and the solute can be liquid, solid or gas. There are many different types of solutions and have many distinct features, but in a broad sense, they can be categorized as True, Colloidal or Suspension solutions.
On the ground of size of the particles, nature of the solution, the ability of diffusion and sedimentation these solutions can be defined. They (solutions) are also differentiated by Brownian motion and Tyndall effect.

Meaning
True solutions are the type of mixtures, where the solute and solvents are properly mixed in the liquid phase.
Colloidal solutions are the type of mixture, where the solute (tiny particles or colloids) is uniformly distributed in the solvent (liquid phase).
The suspension is the mixture, where the solute does not get dissolved, rather get suspended in the liquid and float freely in the medium.

Starch dissolved in water.
Soil dissolved in water.

Definition of True Solution
The homogenous mixture of two or more substances, where the solute is dissolved in the solvent is called the true solution. Here the size of the particles is less than 1 nm. The example of the true solution is when sugar or salt dissolved in water. The particles cannot be filtered or separated through filter paper or parchment paper. Even the particles are invisible through naked eyes.
As the mixture is in the liquid phase and transparent, it allows the light to pass through the solution without getting scattered. When the solution is said as homogenous, it means the particles are evenly distributed in the solution and do not get settled at the bottom of the container. As the amount of particles present in per unit volume of the solution is equal everywhere, the particle density is higher.
The separation of the colloidal particles can be done through parchment paper, but not through the filter paper. The particles can be obtained by the process of centrifugation, where they (particles) will get settled at the bottom. As the mixture is the heterogeneous type, the particles are not evenly distributed in the solutions.
Definition of Colloidal Solution
The heterogeneous mixture of two or more substances, where the size of the particles lies between 1- 1000 nm, is known as a colloidal solution. The colloidal solution is the intermediate between true solution and suspension, though it is also in the liquid phase. When starch dissolved in water or Gelatin mixed in the water are the examples of the colloidal solutions, here the tiny particles will float instead of getting dissolved.
As the colloidal solutions are translucent, they allow the light to pass through the liquid, but due to the presence of particles, the light gets scattered. Brownian motion and Tyndall effect is observed in Colloidal solution. Emulsion, Foam, Sol, Hydrocolloid, Reversible or Irreversible Colloids are the various types of colloids.
Definition of Suspension
Suspensions are the mixture, where the size of the particles is more than the 1000 nm. When the soil is dissolved in water, which is stirred strongly, after some time the particles of the solution gets settle at the bottom of the container due to the gravity; This is the example of the suspension.
